After the output has been turned off, this LED lights green for a predetermined
time if the hard arc count limit was reached during the previous run. You define
this limit. The ARC LED will be activated under two different conditions:
1. If the hard arc count limit is non-zero and the number of hard arcs seen
exceeded this limit during the last run, the pulse will occur when the output is
turned off.
2. If the hard arc count limit is set to zero, this signal will pulse for a
predetermined time for every hard arc seen by the unit. If another hard arc is seen
before the last pulse is complete, the pulse width will be refreshed to the full
width.
